引入三维实体单元模型和子结构分析方法，提出了大功率汽轮机叶片组静频和动频的计算方法．文中对一工程中实际使用的长叶片组进行了分析，实例分析表明，文中所提供的分析模型可以充分利用现有的计算工具精确分析叶片组的振动特性，直观地反映叶片的应力状况和振动形态
The three-dimensional solid element model and substructure analysis method are introduced, and the calculation methods of static frequency and dynamic frequency of high power steam turbine blade set are proposed. In this paper, an actual long blade group in a project is analyzed. The example analysis shows that the analysis model provided in this paper can make full use of the existing calculation tools to accurately analyze the vibration characteristics of the blade group and visually reflect the stress state and vibration of the blade form
